Vistara — Awaiting for my ticket

On 5-8-20 i did a booking for my flight uk902 from mumbai to delhi scheduled on 7-8-20 i did the complete payment and procedure on vistara website my money got deducted but instead of getting a ticket i got a mail saying that i have to contact the company payment office for the matter and the site is not showing my information at all it says that i didn't even booked a flight. I also contacted the vistara air help but no response from there.
Please look into this matter it's a straight up fraud going on.
